Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

One of the research direction of Horst Lippmann during his whole scientific career was
devoted to the possibilities to explain complex material behavior by generalized continua …

SUMMARY A hierarchical multiscale framework is proposed to model the mechanical
behaviour of granular media. The framework employs a rigorous hierarchical coupling …

This article focuses on computational multiscale methods for the mechanical response of
nonlinear heterogeneous materials. After a short historical note, a brief overview is given of …

This paper presents a novel two-dimensional (2D) discrete model for granular materials with
rolling resistance. The salient features of our formulation are: it consists of a geometrically …

Explicit and closed expressions for the stress and couple-stress fields for discrete (classical)
mechanical systems in terms of the constituents' degrees of freedom and interactions are …

" Creep Modeling for Structural Analysis" develops methods to simulate and analyze the
time-dependent changes of stress and strain states in engineering structures up to the …

Based on numerical experiments using the distinct element method, revised with the
capillary water contact model proposed, this paper presents an insight into the shear …

In Mechanics, material properties are most often regarded as being given, and based on
this, many technical solutions are usually conceived and constructed. However, nowadays …

Precise knowledge of the post-peak constitutive response occurring within shear bands in
sands is of keen interest in geomechanics, particularly for accurate modelling of progressive …
